Description
We discuss the possibility of a First Order Electroweak Phase Transition (FOEWPT) in the early universe, as required for EW baryogenesis, in the framework of the 2HDM. One corresponding prediction, the decay $A \to Z H$ with $H \to t \bar t$ may have been observed at the LHC. We present the phenomenological consequences for the detection of gravitational waves at LISA, as well as the prospects for the HL-LHC.
